Is Angelina a big meanie?

Angelina Jolie is cruel, cold and controlling, claims a former bodyguard for the superstar.

The bodyguard, going only by the name "Bill", told InTouch that Jolie's caring, philanthropic public persona is a scam and that the real Angelina Jolie is cold, calculating and even cruel to her own children and partner Brad Pitt.

"Angelina has a public and a private persona," the bodyguard said. "In my opinion, the real Angelina is self-centered and a control freak. She has no patience at all. She doesn't do things out of the kindness of her heart. And she's totally psycho."

Bill claims Jolie easily flies off the handle with her six children, while Pitt is by far the calmer, more laid-back parent. "She screams and yells a lot, then walks away," Bill said, and then the actress would "disappear into her suite for hours... She would punish them with silence. I think she could be abusive at times in a mental way."

The bodyguard also said that Jolie is utterly unmoved by her children's tears in the face of her emotional withholding. "She is not moved by tears," Bill said -- adding that she has a "quirky habit" of "giggling when one of her kids would start crying."

While Brad and Angelina enjoyed quite the honeymoon period when the two were carrying on a clandestine affair just before and during his breakup with Jennifer Aniston -- sources heard them on vacation having crazy monkey sex -- Bill says the honeymoon was over long ago.

Now the pair sleeps in separate rooms, the bodyguard claimed, and Pitt lives in dread of Jolie's phone calls. "She'll call him from the set to interrogate him," Bill said. "His face goes white, and he just stares at his feet."

When he's had enough Pitt will "put her on speaker and walk away from the phone. Jolie will hang up and continue calling until one of the staff picks up."

Last year Pitt and Jolie successfully sued to stop the publication of a tell-all book by another bodyguard.
